' Specification of Letters Patent.

Application filed December 10, 1907. Serial No. 406,860.

Duquesne, Allegheny county, Pennsylvania, have invented a, new and useful Improvement in Blast-Furnace-Charging A paratus, of which the following is a ful clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, 1n which 4 Figure 1 is a side elevation partly in section of a lorry or scale car constructed in osition on' t e lorry car track which o'cated beneath the stock bins; Fig. 3 1s a plan .view partly in section showing the? removable stock receptacles mounted on the car and showing the turning mechanlsm by which these receptacles are rotated on the car. i a

My invention relates to a ployed in charging stock into aratus em ast furnaces and in distributing stock charged into such furnaces and is designed to provide an improved apparatus which will distribute the stock in any desired manner Within the charging buckets or receptacles in which the stock is carried to the top of the furnace, and to provide apparatus which will permit of the stock being distributed at the base of the furnace where it is under the 'eye and control of the operator.

The invention is further desi ned to provide a simple and effective distributing apparatus which can easily-be applied to and used with the hoisting apparatus used on existing furnaces, one form of such hoisting apparatus being shown and described in Patent No. 579,011, granted May 16th, 1896.

to "William Rotthofi and Marvin A. N eeland.

In the drawings, 2 represents the body of the lorry or scale car having'wheels 3 which are mounted to run upon the rails 4 forming the lor track. The lorry track extends from in rout of the stock bin, where the stock receptacles are filled to a point below the foot ofthe inclined track or hoist u on which the filled stock receptacles are li ted from the lorry car and are lifted to the top of the furnace where the, buckets or rece tacles are discharged intothe furnace. T e car 2 s provided with a driving motor 5. which Is connected by suitable slow-down gearing with the axle 6 on the front wheels of each wheel truck'under the scale car. .The lorry car is preferably (provided with a scale mechanism inter ose between the platform 7 and the car ame 2, the platform being sus pended from the frame 2, although the weighing mechanism may be omitted in which case the platform 7 and supporting beams 7 will be rigidly secured to the car body 2. As shown the platforms 7 are supported on beams 7 which are connected by the brackets 7 to the scale levers 8. One

eye-bolts 2 to the car body 2, the movable ends of the scale levers 8 are connected ina suitable manner with the multiple levers 8, the multiple levers being fulcrumed to the overhanging beams 2 which are carried on the car body 2. The movable ends of the multiple levers 8 are in turn connected to the scale lever 8 which is' fulcrumed to an overhanging beam 2 on the car body 2 and the moving end of the lever 8 is connected by the rod 8 with the finger beams 8 which are 10- cated in a beam box 8 on the lorry car2.

supports 9 which carry the removable buckets' or stock receptacles 10.. The bucket supports 9 are provided with vertical shafts 11 the platform 7 so as to be rotatable. .tifrictlon rollers 12 are provided between the latform 7 and bucket sup orts 9 so as to essen the friction when the ucket supports 9 are rotated. The peripheries of each of the supports 9 are provided with spur-gear teeth 13 which mesh with the teeth in the spur pinpinion 14 is mounted on the vertical shaft 15 bevel gear 17 on the slow-down mechanism connected with the driving motor 18.

both of the spur-gears, a separate motor ma be em loyed for each of these gears in whic case they may be rotated independently.

The stock receptacles 10 are rovided with drop bottoms 19, each of these ottoms havead on the top of these rods which en-l gages with a hook on the trolley by which the clined hoist the top of the furnace.

endof the levers 8 is pivotally connected by ions 14. 14' andas shown in Figs. 1 and 3, the

Instead of having one motor 18 to rotateing a vertical post orrod 20 and preferably a receptacles are lifted from th car to the in-;- and are carried on the hoist to On the platforms 7 are rotating bucket which are secured in the central bearin s in v which is provided on this lower end with a bevel gear 16 which meshes with a similar Suitable controllers 21 are provided by which the motors used on'fthrcar are oper- Med and controlled, and a hand brake 22 one of the spouts 24 on the stock pins 25 to receive the materials discharged from .the

- spout. The gates of the stock bin 25. being o ened, the materials are then delivered into t e bucket 10. This bucket or receptacle may be constantly rotated while it is being filled, causing the material to be deposited in such manner that there is formed a-spiral column of coarse material and also one of fine material. It is evident that the more revo lutions the bucket makes the nearer equal will be the proportions of coarse and fine material in each vertical plane passing through the center of the bucket. Or the bucket may be held stationary while being filled, in which case the rece' tacle is rotatedbefore and after being filled? The second of the receptaclcslO is filled in a like manner and the car is then moved on the track until the receptacles are in position to be removed from the car and be hoisted to the top of the furnace by the usual hoisting mechanism. The buckets 10 are placed in position on the top of the furnace hopper by the trolley and the bottoms 19of the buckets are then lowered so as to permit the materials to flow from the bottom of the bucket in an annular sheet into the furnace hopper. After the buckets are emptied at the top of the furnace, they are lowered by the hoisting apparatus and are again re laced on the car when the above described operations are repeated.

When' thereceptacles 10 are not continu-.

ously rotated while being. filled, they are caused to rotate through a part of a revolution so as to bring the buckets into different positions between the time the bucket is relaced upon the car after being hoisted to the 4 urnace top and the time when it is again in position to be lifted, inthis way ,changin gthe relative angular position of the imaginary vertical plane dividing the coarse, lumpy materials and the finer materials in the successive receptacles and changing the relative position of the lump materials in successive charges emptied into the top of the furnace.

The advantages of my invention are many and will be apparent to those skilled in the art.

. 1 Instead of employingthe iii'depende'nt distributing mechanism as has heretofore been necessary, the distributing mechanismis car- 'ceptacles. The manner of distributing the stock may be varied as is desired.

The apparatus is sim 1e and 1s easily kept in repair and by the a dition-of the turning.

mechanism to the lorry car my improved apparatus may be applied to any ofthe existing stock charging arrangements which are in.

part of the scale proper, may be omittedan an ordinary latform scale located in the track leading from the stock bin may be used and many other changes may be made. 7
